Research suggests that individual differences in math abilities correlate with approximate representations of quantity that are supported by a primitive Approximate Number System (ANS). However, relatively little research has addressed the direction of this association in early childhood. Here we examined the development of the ANS and math…

Elementary schoolchildren's working memory performance (WMP) fluctuates from moment to moment and day to day, yet the underlying mechanisms are not well understood. In the present study, affective states were investigated as predictors of these fluctuations. Interindividual differences in the intraindividual affect--WMP associations were expected,…

An enduring question is whether language learning aptitude is a stable trait or is one influenced by experience, such as living with two languages. We investigated aptitude in bilinguals and treated their bilingual experience as an aggregate of variables, focusing on how individual differences in (a) language experience variables of proficiency,…

Promotion with tenure is often the ultimate goal for PhD students who choose to pursue a career in higher education. Extensive mentorship is provided for tenure-track faculty to smooth the path toward promotion with tenure, but most faculty members achieve this goal relatively early in their careers, leaving years if not decades ahead in a tenured…

How people learn to read is an interesting question which has been investigated by many studies with various approaches. Some recent studies have related learning to read with domain-general abilities and have found a positive relationship between statistical learning and learning to read, as well as between procedural learning and learning to…

Experiences of contingent responsivity during shared book reading predict better learning outcomes. However, it is unclear whether contingent responsivity from a digital book could provide similar support for children. The effects on story recall and engagement interacting with a digital book that responded contingently on children's vocalizations…

Purpose: It is generally accepted that adults use visual cues to improve speech intelligibility in noisy environments, but findings regarding visual speech benefit in children are mixed. We explored factors that contribute to audiovisual (AV) gain in young children's speech understanding. We examined whether there is an AV benefit to…

Many interventions are characterized by repeated observations on the same individuals (e.g., baseline, mid-intervention, two to three post-intervention observations), which offer the opportunity to consider differences in how individuals vary over time. Effective interventions may not be limited to changing means, but instead may also include…

Proponents of character education claim cultivating virtues during schooling helps students, schools and society flourish but critics argue character education programs implicitly justify social inequality by assuming success or failure in life is due to individual character. There is little empirical research about which individual factors, such…

Background: According to self-determination theory [Richard M. Ryan and Edward L. Deci. 2017. "Self-determination theory: Basic psychological needs in motivation, development and wellness." New York, NY: Guilford], teachers' interpersonal behaviors would relate to students' behavioral outcomes in physical education. Although a body of…

Recent years have seen a growing research interest in the notion of directed motivational currents (DMCs) that defines highly intense motivational surges oriented to a much-desired goal of personal significance. However, the learner characteristics that induce individual-level variability in DMCs have yet to be explored. In particular, the role of…

Widely implemented in Europe over the last three decades, Content and Language Integrated Learning (CLIL) has been researched in some European contexts more extensively than in others, with the Norwegian context being among the least represented. This paper attempts to contribute to filling in the gap by examining the impact of a short-term CLIL…

Purpose: This case-control study sought to determine if (a) children with childhood apraxia of speech (CAS), other speech sound disorders (SSDs), and typical development would perform differently on a procedural learning assessment and (b) whether grammatical ability would impact group differences. Method: Communication, motor, and procedural…

These are the appendixes for the report, "How Nebraska Teachers Use and Perceive Summative, Interim, and Formative Data." This document presents additional information about the study topic: teachers' data use. It begins with a description of the conceptual framework and supporting literature for the scales in the Teacher Data Use Survey…

The current laboratory-based study examined individual differences in sadness coherence (i.e., coherence between objectively coded sad facial expressions and heart rate in response to a sad film clip) and associations with dispositional affect (i.e., positive and negative affect, extraversion, neuroticism) and age in a sample of younger and older…
